Abstract:
An interconnect structure is provided that includes a dielectric material (52) having a dielectric constant of 4.0 or less and including a plurality of conductive features (56) embedded therein. The dielectric material (52) has an upper surface that is located beneath an upper surface of each of the plurality of conductive features (56). A first dielectric cap (58) is located on the upper surface of the dielectric material (52) and extends onto at least a portion of the upper surface of each of the plurality of conductive features (56). As shown, the first dielectric cap (58) forms an interface (59) with each of the plurality of conductive features (56) that is opposite to an electrical field that is generated by neighboring conductive features. The inventive structure also includes a second dielectric cap (60) located on an exposed portion of the upper surface of each of the plurality of conductive features (56) not covered with the first dielectric cap (58). The second dielectric cap (60) further covers on an exposed surface of the first dielectric cap (58).
Abstract:
Es wird eine kohlenstoffreiche Carbobornitriddielektrikum-Dünnschicht (14) mit einer Dielektrizitätskonstante von gleich oder kleiner 3,6 bereitgestellt, die als Komponente in verschiedenen elektronischen Einheiten verwendet werden kann. Die kohlenstoffreiche Carbobornitriddielektrikum-Dünnschicht weist eine Formel CxByNz auf, wobei x 35 Atomprozent oder mehr beträgt, y von 6 Atomprozent bis 32 Atomprozent beträgt und z von 8 Atomprozent bis 33 Atomprozent beträgt.
